The Candida albicans is a diploid polymorphic yeast that is found as part of the normal microbial flora in most healthy humans. It’s usually a harmless colonizer of mucosal surfaces; it can, however, cause disease in the case where the host suffers from a weakened immune system or is immunocompromised. The present investigation was carried out to detect and investigate the prevalence of some virulence factors, which include coagulase production, biofilm formation, and phospholipase distribution among Candida albicans isolated from different clinical samples, including oral cavity and respiratory tract, which were collected from May to August 2022 and numbered 280 of different ages and genders of Iraqi patients suspect

Show MoreThis study included the preparation and characterization of the new guanine derivative (N-((6-oxo-6,9-dihydro-1H-purin-2-yl)carbamothioyl)propionamide), with an exciting chemical structure. The guanine part is a bicyclic heterocyclic base that is connected to a carbamothioyl group by a propionamide linker. This nitrogenous base derivative is prepared in two steps: The first step involves the synthesis of propionyl isothiocyanate from the reaction of propionyl chloride with ammonium thiocyanate in acetone. In contrast, the second step consists of the reaction of ammonium thiocyanate with guanine to obtain the ligand.
